Nope. This is a misconception.

Batteries don't have rare-earth materials in them. Lithium, nickel, and iron are very plentiful in the US. The "rarest" of materials that might be mined is Cobalt. That, however isn't because it's a hard to find. Rather, cobalt has basically no industrial applications outside of battery production. And, importantly, not all battery chemistries require cobalt, just the nickel manganese cobalt batteries.

Idaho has a cobalt mine that's not currently in operation. The reason is because demand is super low and the artisanal mines in africa are cheaper than spinning up a full industrial mine.

> artisanal mines in africa

Just want to say this is an entertaining euphemism. It isn’t that labor conditions are poor and work is done by hand, it’s “artisanal mining”.

Cobalt is a part of high speed steel and all kinds of metal alloys that have specialized applications, almost 40% of cobalt is used for metallurgical purposes.
